Struct I2cInterface 

pub struct I2cInterface<I2C> { /* private fields */ }

I2C interface for the ICM-20948

Implementations

impl<I2C> I2cInterface<I2C>

pub const fn default(i2c: I2C) -> Self

Create a new I2C interface with the default address (0x68, AD0 pin LOW)

This is the most common configuration where the AD0 pin is pulled low or left floating (has internal pull-down on most breakout boards).

Arguments

• i2c - The I2C peripheral

Example

let interface = I2cInterface::default(i2c);
let mut imu = Icm20948Driver::new(interface)?;

pub const fn alternative(i2c: I2C) -> Self

Create a new I2C interface with the alternative address (0x69, AD0 pin HIGH)

Use this when the AD0 pin is explicitly pulled high to VDD.

Arguments

• i2c - The I2C peripheral

Example

let interface = I2cInterface::alternative(i2c);
let mut imu = Icm20948Driver::new(interface)?;

pub const fn new(i2c: I2C, address: u8) -> Self

Create a new I2C interface with a custom device address

This allows specifying any I2C address for advanced use cases. For standard ICM-20948 configurations, prefer default() or alternative().

Arguments

• i2c - The I2C peripheral
• address - The I2C device address

pub fn release(self) -> I2C

Consume the interface and return the I2C peripheral

Trait Implementations
